  • Continuous process and apparatus for recovering metal from metal and organic waste, by combustion of organic constituent of waste in rotary tube furnace
    Patent number: 7976611
    Abstract: Process for recovering metals from metal-containing wastes and materials, characterized in that the metal-containing waste is preferably introduced continuously into a process chamber, treated thermally with continuous intensive mixing, the organic components are continuously removed and subsequently oxidized and the metal-containing components, preferably as metal conglomerates, and the further inorganic metal-free components are discharged essentially continuously from the process chamber and a plant for carrying out the process.
    Type: Grant
    Filed: April 25, 2006
    Date of Patent: July 12, 2011
    Assignee: Currenta GmbH & Co. OHG
    Inventors: Joachim Beyer, Walter Leidinger, Wolfgang Calaminus, Egidius Vickus, Wilhelm Kuckelsberg, Mark Mätschke
